I have a trailer with the Hobie Trailer Saddles bolted to thecrossframes. The rear saddle has three fibreglas columns holdingthe molded-carpeted saddle. There are no drain holes for the columns except for the bolt holes themselves!If you tighten up the frame bolts, there is no good drainage from thecolumns!I found the taller, central column had collected water and had not drainedeven after 12 hours!

I recommend a small drain hole be drilled horizontally near the bottom ofall five bolt columns to drain water away.

The retention of water in the columns could do real corrosion especiallyif the trailer saddles have gotten saltwater dripped on it from the AI hull.
